Three-quarter plate keywound 16-size movement with twin trains driven by going-barrels, the independent train working by the action of a fly being released by the escape wheel pinion, with cap jewels on balance (diamond), lever and escape and rear hand set square. Single-roller detached lever escapement. Compensation balance, spiral balance-spring. Double-sunk enamel dial, blued-steel hands. 45 mm diameter, 9 mm deep, not including centre arbor.
Vale & Rotherham, later Rotherhams, one of the most important English (Coventry based) watch manufacturers and one of the first to bring American machine-made manufacture to England. This is one of only two examples of its type I have seen. NB: Coventry based, but with a London office at this period, Rotherhams movements often bear ‘London’ on them. This was because it was still a most advantageous place name to use when marketing watches – as did George Daniels in much more recent times.
Hair cracks to dial and mismatched hands, otherwise in good original condition. Not cleaned by me but will just about tick, dial down, when wound – the independent train also complete and tries to work. Sold as needing at least servicing and fresh oil to work correctly.
